What should I make the description of this book?

I'm writing a crossover fanfiction between Glee and Titanic, and I want the description to be like, not totally lame. You know how some descriptions on unprofessional books are like, "What happens when the New Directions are transported to another world, specifically The Titianic? Hilarity, sadness, and death, that's what!" ? I don't want that. Also, I need help on what to call it, so thanks for any help. Bai! :)
